Like no ordinary bull pup, the RDB series of rifles redefines the platform. You've never experienced balance or a trigger quite like this in any other design. The RDB is completely ambidextrous due to its patented downward-ejection, magazine catch/release placement, intuitive safety and reversible operating handle. The RDB series of bull pups delivers a 5.56/.223 ballistic advantage in a very compact package that's easy to manipulate for just about anyone. The RDB Defender is the result of taking the RDB and the RDB Survival and mashing them up to forge the perfect 5.56, light-duty, tactical bull pup. It's lightweight, comes standard with an aluminum, M-LOK handguard, collapsable stock and 16 inches pencil profile barrel. Defend your property, your community and your homeland with the most tactically versatile bull pup on the market with the RDB Defender. Features: Downward ejection - this unrivaled design sends spent brass downward through the stock, behind the magwell making it a truly ambidextrous bullpup rifle Unparalleled trigger system - bullpup triggers are notoriously bad, so we tackled that issue head on and won Adjustable gas system - all of the RDB models operate off of the same adjustable gas piston system This feature allows the user to tailor the bolt carrier speed to eliminate excessive recoil while running a suppressor and ensure reliability for various loads This trigger is incredibly smooth, with a nice take-up and clean break, combined with a 1:7 twist barrel, all RDB models offer excellent accuracy
